Question

我有使用Spring，Apache CXF和Jetty的Web应用程序。 Spring不喜欢在我的一个类中为方法添加一个名为@Loggable的注释。

首先，注释@Loggable链接到类LogAspect，它记录请求和响应消息：

@Aspect
@Component
public class LogAspect {

     ...
     ...
        @Around("execution(* * (..)) && @annotation(Loggable)")
        public Object logAround(ProceedingJoinPoint joinPoint) throws Throwable {

          ...
          if ( returnValue != null) {
                logger.infoRequestResponse(clazz, name, joinPoint.getArgs(), returnValue);
          } else {
                logger.infoRequestResponse(clazz, name, joinPoint.getArgs(), "void");
          }
          return returnValue;
        }
}

我猜它与@Context - 注释有关，以及在什么时候注入的内容。

该类是RESTful服务的实现。私人会员request上有注释@Context：

@org.springframework.stereotype.Service(value = "resellerService")
public class ResellerServiceImpl implements ResellerService {

    @Context
    private HttpServletRequest request;
...
...
    @Loggable
    @Override
    public Response isUserLoggedIn() {
        Optional<ResellerSession> maybeSession = getSessionFromContext();
        return Response.ok(maybeSession.isPresent()).build();
    }

在@Loggable方法上添加isUserLoggedIn - 注释会产生以下异常：

所以我尝试在请求中删除@Context，然后将其添加到setter方法中：

private HttpServletRequest request;

@Context
public void setRequest(HttpServletRequest request) { this.request = request; }

这给了我这个例外：

任何人对如何解决这个问题都有任何想法？

修改

我无法显示我的整个pom.xml，但我确实有这一行 4.1.6.RELEASE

构建看起来很好。所有其他注释，如@Autowired都可以。

Answer 1

问题在于spring-beans-4.1.6.RELEASE.jar。

希望你添加了Spring-beans-4.1.6.jar文件Still Spring有时因某些问题无法获取jar。在这种情况下

从服务器中删除现有项目。

右键单击您的服务器，

点击清理，

右键单击您的服务器，

单击清除工作目录。

Spring MVC也可以这种方式获取jar文件，它可以正常工作

右键单击Spring MVC项目，

构建路径 - ＆gt;配置构建路径

将出现一个标签，

选择添加外部JAR按钮并添加所需的所有jar。

之后，单击Deployment Assembly，

单击“添加按钮”，

单击Java Build Path Entries，

单击“下一步”，

选择此窗口中显示的所有jar。

单击“完成”。

刷新您的项目，

运行项目。

截至目前，它将以正确的方式获取spring-beans-4.1.6.RELEASE.jar。希望它有所帮助。

Answer 2

我现在已经收到有关如何解决此问题的帮助。简而言之，必须将@Context注释移动到类实现的接口的方法中。

解决方案如下：

删除了私人成员HttpServletRequest request及其@Context注释。
将HttpServletRequest参数添加到使用它的方法中。例如：

public Response registerUser（HttpServletRequest request，...）{
将@Context注释添加到REST界面。例如：

@Path（＆＃34;寄存器/用户＆＃34）
@POST
@Consumes（＆＃34;应用/ JSON＆＃34）

响应registerUser（@Context HttpServletRequest httpServletRequest，..）;

来自Spring的BeanCreationException，注释为“@Context”和“@Loggable”
